Mapping Sol

Well, too high a partial pressure of oxygen -is- poisonous (same for carbon dioxide, actually). But I don't think I've read anything like Narf's statement.

Heh...

Too much oxygen is poisonous because we've evolved in this atmosphere which is 70 percent+ nitrogen. A (nearly) pure oxygen atmosphere would not necessarily be impossible for life to exist in, though unlikely in 'real life' because free oxygen is chemically unstable. It's the presence of life that maintains the current percentage of oxygen in Earth's atmosphere now. It would all be soaked up in chemical compounds within a few million years without constant renewal by plants. Many simpler life forms on Earth today could handle a nearly pure oxygen atmosphere, though.

It's much the same for CO2. We humans would die in an atmosphere of more than 4 or 5 percent CO2, as I recall. This is not a universal constant but simply a function of how human physiology turned out. Lots of simpler animals can handle more than 4 or 5 percent CO2.

You want to map the sol system only??? Got 10 minutes to spare? Now if you want to map the closest 100 systems that would be a really cool project!

(one I've thought about doing myself but that map editor

... )

yeah, to high oxygen = bad.

Should there be 8, 9, or 12 planets?

How many moons should be included? Would Phobos and Deimos be included, or would they be considered asteroids?

Earth should be an Oxygen planet - Medium sized IMHO.

IMO, there should be 9 Planets. Quaoar is technically a Kuiper Belt Object. Although Pluto and Charon are also Kuiper belt "objects", but they've been classified as a planet for a long time, so should be treated as a planet.

The larger moons should be included IMHO: This includes The Moon, Charon, all larger moons of Jupiter and Saturn: Europa, Ganymede, Io, Titan, Etc. Deimos and Phobos shouldn't be included in the map, since they are asteroids.

Just my two cents.

You could always make a random map and just move the systems around and rename them.

Yea that would be cool. Now can someone else do it?
